Is 2 servings of protein powder excessive?

Side effects to high protein diet.
Flatulence, and a lot of it.

Ketonuria.

Competing body builders Dietary protein intake is recommended to be 1.6–2.2 g/kg/day with a focus on sufficient protein at each meal (0.40–0.55 g/kg/meal) and an even distribution throughout the day (3–6 meals). You weigh 185 lb, that'd roughly 84kg x 1g/kg = 84 grams of protein per day for average well exercising Joe.

Are you taking 52 grams of powder or 52 grams of protein?

Usually on a problem with certain proteins or lower quality whey concentrate.

Ketonuria.

You'd have to be taking an absolutely absurd amount.

Current research suggests that while limiting protein intake from red meat sources can be helpful, dairy protein (which is what is often supplemented) intake seems to have little effect on kidney function.

Someone who is exercising regularly is going to benefit from more than 100g of protein per day unless they are very small.



Not true at all. The two most popular protein powders are whey and casein which are just isolated from dairy milk and packaged.

-Having cared for many pts with liver or kidney failure, I can assure you there are noticeable benefits to limiting protein intake. It does not improve the kidney or liver, but keeps the work load in the manageable range, limiting the effects of uremia.

We only need protein in the diet to supply the nine essential amino acids- several of which are absent in the more popular veggies. We can make all the other ones out of glucose. Those who exercise more need a lot more extra carbs than extra protein in their diets. Most of that extra protein will be turned into glucose anyway.

Regardless the source of the protein for the supplements, they are still just hydrolyzed, dehydratd and canned. Your liver can do the hydrolyzing and then it doesn't have to be dehydrated or canned. Save your money.

Be that as it may, it isn't really relevant to anyone who isn't dealing with impaired kidney function.

The pathway to convert protein to glucose exists, but it isn't particularly efficient. Most of it is just oxidized. I do agree that proper carb intake is essential, as once the protein requirements are met, carb intake drives growth better than more protein. Still, you're talking about after reaching that 1g/lb of LBM threshold.

Most protein supplements are not hydrolyzed. They exist, but they are a small niche product and they've fallen out of favor over the last decade or so as their primary claimed benefit (faster digestion) turned out to be inconsequential.

I also don't see money as a concern. On a unit cost, you can buy bulk whey or casein protein powders for fair cheaper than you could with whole foods of a similar protein level. There really isn't a downside to using protein supplements and there are several advantages.
